ERP

• ERP

  Event Related Potentials

  • this is what’s left when all e transoms activity from an EEG recording is filtered out.
  • using a statistical technique, this leaves only the responses that relate to the presentation of a specific stimulus
  • are a type of brainwave that are triggered by particular events
  • research has revealed many different forms of ERP and how they’re linked to cognitive processes
• +measures of neural processes are more specific that EEGs

  +temporal resolution is better than fMRIs

  As a result, ERPs are frequently used in cognitive research.
• -lack of standardisation makes it difficult to confirm findings

  -background noise and extraneous variables must be completely eliminated

  This may not always be easy to achieve.
